Rich, excellent topic - and, hello!
A few weeks ago I did some reading on the WT and occult symbolism in their publications. I approached the reading with a sceptical stance. When done, I came away with the sense that the illustrators have a dark-humored commedian or two among them - probably some underrecognized artist getting some satisfaction by puttin' one over on the old geezers. But I'll say that this person(s) knows a bit about their occultic symbolism.
It seemed that the book with the largest amount of symbolilsm subliminally inserted into illustrations was the 'Revelation Climax' book. But there are other examples in the 'Live Forever' book:
page 19: The stolen jewelery is in shapes used in occult (frankly, I didn't believe it myself until I read a comparison of the triangular pendant and a specific occult symbol)
page 93: The background waterfall is a skull
There are others in that book. But without some furter explanaiton, they will look like just so much shadow and fabric draping.
Its the kind of stuff that one can decide not to see. I am certain that some of the symbols I've read about are in the illustrations as a coincidence. But I am equally certain that some are intentional. However, the reading I have done contains little explanation of motive or effect. so again, I think it is an illustrator with a (bad?) sense of humor.
